Problems solved by technology

However, there is a likelihood of scrap generation during the fabrication process for the electro luminescent display and the resistive touch device on the two surfaces of the transparent substrate.
In addition, the resistive touch device has a poor sensitivity.
However, the resistive touch screen possesses a poor sensitivity and requires the user to use a tip of pens touch to indicate the touch site, and using the resistive touch screen is likely to generate scrap.
In addition, it is likely to damage the resistive touch screen when the cap is used to encapsulate the organic light-emitting display.
However, the fabrication processes disclosed by US 2004 / 0080267 A1 is very complicated, and the lifetime of the organic light-emitting display is shortened due to the fabrication of the resistive touch screen on the transparent cap of the organic light-emitting display.
In addition, the resistive touch device has a poor sensitivity.

Description

BACKGROUND OF THE INVENTION[0001](A) Field of the Invention[0002]The present invention relates to a transparent touch panel, and more particularly, to a transparent touch panel incorporating a capacitive touch device and a display device.[0003](B) Description of the Related Art[0004]With the increasing demand for multimedia message technologies, the touch screen is widely utilized to replace the keyboard and mouse as the information-inputting device. This change is due to the fact that the touch screen is simple, small, and complies well with human nature. The touch screen has been widely applied to the tourist-guiding system, automatic teller machine, palm computer, vending machine, and industry control systems.[0005]US 2002 / 0186208 A1 discloses an electro luminescent apparatus including a transparent substrate, a resistive touch device positioned on one surface of the transparent substrate, and an electro luminescent display on another surface of the transparent substrate. However...
